GaAs IC 35 dB Voltage Variable Attenuator
Single Positive Control 0.5–2.5 GHz
Features
I Single Positive +5 V Control Voltage
I 35 dB Attenuation Range @ 0.9 GHz
I Less Than ±1 dB Attenuation Change Over
Temperature
I Excellent Linearity Performance
Description
The AV103-12 GaAs IC FET voltage variable attenuator
provides 35 dB attenuation range at 900 MHz controlled
by a single positive voltage. The VVA has a linear transfer
curve of 9 dB/V slope, with input and output VSWR better
than 2.1:1 over all states. Its attenuation range at 1900
MHz is 33 dB. It operates with supply voltage of +5 V and
control voltage of 0 V to +5 V in a low cost SOIC-8
package. The RF ports require 100 pF DC blocking
capacitors.
